Under tropical soils, the precise requirement of inorganic fertilizer and its possible substitute is yet to be
validated for the production of Amaranthus cruentus L. The nutrient requirement of A. cruentus under two soil types and yield quality under field conditions. Field experiment was conducted at two locations in Lagos State: Ikorodu (Orthic Luvisol) and Lagos State (LASU) Ojo Campus (Dystric Fluvisol) to investigate the effects of organic and organomineral and NPK fertilizer treatments on the quality of Amaranthus cruentus L. Eight fertilizer treatments. (1) Control (no fertilizer), (2) Pacesetter’s Grade B (PGB) 100 %, (3) PGB + NPK (75:25), (4) PGB + NKP (50:50), (5) Kola Pod Husk (KPH) 100 %, (6) KPH + NPK (75:25), (7) KPH + NPK (50:50) and (8) NPK (100 %) were tested at first planting. Residual effects of the fertilizers were assessed in the second and third planting periods. The experiment was arranged in a randomized complete block design in four Replications. Parameters assessed include proximate analysis. Data were analysed using ANOVA. The KPH + NPK (75:25)resulted in significant (p<0.05) higher crude protein content (19.8 and 14.9 %), ether extract (8.5 and 8.2 %) while crude fibre (9.5 and 10.8 %) was lower than control at Ikorodu and LASU respectively. The KPH and PGB had high potential in A. cruentus production. At Ikorodu, KPH + NPK (75:25) was the best while at LASU, PGB + NPK (75:25) was optimum. KPH + NPK (75:25) gave highest crude protein content, ether extract and lowest crude fibre in A. cruentus.
